JFK almost launched off a nuclear conflagration and is considered one of the best american presidents. Donald Trump isn't even near average. These are impossibly stressful decisions in which literally millions of lives lie in the balance. I trust McMaster and Mattis..but at the end of the day the President makes the decisions. During the cuban missile crisis THE JOINT CHIEFS pushed HARD for a full out attack on the cuban mainland. JFK was almost swayed. I think it is very reasonable to ponder whether or not a 71 year old reality television star who is very clearly quite emotional...is capable of winning bets of this nature. Decision making under uncertainty is hard for even the best of us. I do not believe he is the best of us.
